Gentlefolk;

Daniel's paean to "pure" pentesting (for lack of any other name) gave
me a great deal of thought. I'm solidly in the "white-hat script
kiddie" working my way into basic attack skills. I've been an
engineer for 12 years and in infosec for the last five.

What I have noted the most is the absolute lack of consistent
training for this artform known as penetration testing. In fact, I'm
not sure it _can_ be taught. It requires an insatiable curiosity and
loads of patience, followed by some healthy adolescent glee. If
that's what can be defined as a "spark," I'm in for the long haul. I
love this stuff.

I'm fundamentally self-taught, doing work for an office where no one
else knows how to do pentesting, other than filling out an audit
checklist **shudder.** My successes are solitary, and while
consistent, I know I am plucking the low hanging fruit. Someone has
to do it, and it's good training for me as I go.

If every engagement means that I learn something, I am content. I am
not in the rarified top ten by any means, but I don't know anyone who
is! I, too, would like to work with someone who knows their stuff,
but the people I meet know as much as me, rarely more.

It's why I'm on this list. So bear with us lowly white hat
scripters, we're at least on the learning curve.

Regards

Dude, this is perhaps the best description of pentesting skillsets
that I've ever seen. I am quite unhappy with where I personally fall
on that scale, but I'm working to improve my position. :) Well said,
man...well said.

Exactly, and I'd add to this that true cracking starts only when
you've run every packaged tool and found NO MAJOR OPENINGS. If you
can get in after finding out that there aren't any massive
vulnerabilities, *then* you can call yourself a pentester. Until then
 
you're mostly just running tools and pressing buttons.

I've cracked a decent number of networks in my time as a professional
 
and I always get praise for it. Although I may have done something
pretty cool stuff to get control of a network (in the few cases where
 
there was at least *some* challenge), the openings I had were always
too large to earn myself any self-respect. It's not cracking if your
first foothold was a vulnerability that lets you use an attack
already in Metasploit. That's just too easy, and if it's easy -- it's
 
not true cracking.

The absolute worst, though, is being called a hacker. It's
despicable. I feel like screaming, "You shouldn't even be allowed to
use that word, let alone give the title to someone else." The
Princess Bride always comes to mind:

Presenter: "This is Daniel, he's a hacker."
Me: "I do not think that word means what you think it means."

So yeah, the differences are very important, as is knowing where you
truly stand. The vast majority of "pentesters" are just security
professionals running security tools; there's no creativity, no
innovation, no spark. Most are actually just kiddies, the next lot
falls above kiddies and below true crackers, then there's the real
elites -- those with 1) the cracker mentality, and 2) the cracker
skillsets. I'm in the upper part of level two I'd say, constantly
heading toward where I need to be. :)

It's interesting that you, Eric, don't call yourself a pentester
either. I do becasue it's my job, but I can't help but feel like the
eternal student with no rights to call myself anything. I use this
feeling to continue growing.

Amen, brother.

Yes. This is what I'm talking about. It's like the most qualified
people have the lowest opinions of their skills. In short, we know
best how little we really do know.

Completely agreed. There's only one problem with your definition --
it only leaves a few hundred people worldwide. I'd submit that you
*can* have people below this uber-elite level offer something
tangible to clients. If you can perform a "pentest" for a client and
uncover deficiencies in their security which they then go on to fix,
you've performed a service that's worth paying for. Would it be
better if it were done by one of the true elites? Sure -- but that's
not to say that the former isn't valuable to some degree.

The problem is there are very few who are even capable of doing
*that* among those that call themselves pentesters. As discussed,
most people with the title are simply running tools. They're the CORE
 
IMPACT class. Point and click, point and click.

Yup.

Seriously...me too. I feel like being a student of the discipline and
 
a "professional" are almost mutually exclusive, and I'm *definitely*
the former. The thing you have to consider, though, is how you
compare to the other "professionals". :) Think of the benefit to the
client moreso than your own personal ranking. If I went by my own
personal standards, I wouldn't be in the field at all. I'd be huddled
 
up over my personal computer lab "getting ready" for the next 15
years.

Same here, and thanks for the most excellent post.
